Factory Price Brand New 6Bt5.9-G1 Engine Assembly for Cum-mins Excavator Loader

This is a brand-new complete 6BT 5.9L inline 6-cylinder four-stroke water-cooled mechanical diesel engine, the classic 12-valve heavy-duty power platform developed by Cum-mins.

• Displacement: 5.9L (5883cc)
• Cylinder layout: Inline six cylinders, 2 valves per cylinder (12 valves total)
• Supercharging system: Equipped with turbocharger for strong low-torque output
• Cooling mode: Circulating water cooling with large cooling fan
• Fuel supply: Mechanical inline injection pump, stable fuel supply, easy maintenance without complex electronic control modules
• Body material: Integral cast iron cylinder block & cylinder head, high structural rigidity, anti-vibration and wear-resistant
• Complete assembly configuration: Comes with radiator fan, dual oil filter assembly, alternator, starter motor, full wiring harness and factory certification documents, ready for direct installation without extra parts matching.

1. Extreme Reliability & Long Service Life

   The all-mechanical structure avoids electronic failure risks. With regular maintenance, its service life can reach over one million kilometers/hours, widely recognized as a durable benchmark for industrial power. The thick cast iron body resists harsh working conditions like dust, high temperature and heavy load.

2. Strong Power & Excellent Torque Performance

   Turbocharged design releases powerful torque at low rotating speed, great for climbing, heavy haulage and heavy-duty construction operations. Multiple power versions cover 160–210 HP to meet diverse load demands.

3. Low Operation Cost & Easy Maintenance

   Mechanical fuel pump structure has simple failure logic, ordinary technicians can complete overhaul and daily maintenance without professional diagnostic instruments. It supports wide-specification commercial diesel, with moderate fuel consumption and low spare parts cost globally.

4. Wide Compatibility & Versatile Application

   Standardized installation interface, universal flywheel housing and output end, perfectly matching multiple equipment types:

   • Construction machinery: Loaders, excavators, road rollers, concrete mixers
   • Commercial vehicles: Medium/heavy trucks, passenger buses, dump trucks
   • Agricultural equipment: Large tractors, harvesters, irrigation pump units
   • Fixed power: Generator sets, industrial water pumps, marine auxiliary power
5. Brand-New Original Factory Standard

   The whole machine is brand-new, original factory assembly with complete qualification certificates, factory test records and matching accessories. Surface anti-rust paint treatment, packed in solid wooden case to avoid damage during transportation.

This 6BT diesel engine assembly is the mainstream power solution for medium heavy-duty equipment worldwide, favored by equipment manufacturers and repair factories for its stable performance, mature supply chain and low failure rate. It works stably under continuous heavy-load operation in mining, infrastructure, agriculture and logistics transportation industries.

• Complete full-set accessories for direct replacement
• Full official certification documents for customs clearance
• Strict factory bench test before delivery to guarantee zero fault on arrival
• Customizable power tuning and interface modification according to customer equipment requirements
• Global after-sales spare parts supply support
